Description

LED base plate structure

technical field

The utility model relates to an LED lamp component, in particular to an LED base plate structure.

Background technique

At present, in the known LED (Light Emitting Diodes) lamp structure, each LED is integrated and assembled on the surface of a base plate, and then the base plate is arranged on a predetermined position of the lamp; the above-mentioned known base plate is often designed It is in a plane shape, so when each LED group is set on it, the projection angles of the light are in the same direction, which causes the problem that the light projection area is concentrated and narrow. Therefore, it is necessary to further adjust the angle of LEDs in local areas during production, which obviously leads to an increase in manufacturing operations, and with the increase in the number of LED installations, the required adjustment man-hours will also be relatively extended. Therefore, the existing LED Base plates do not have good industrial economics.

In addition, some manufacturers try to produce reflectors with larger refraction angles in order to produce a wider light projection effect. However, reflectors with larger refraction angles will relatively reduce the intensity of the irradiated light, and thus cannot really achieve good lighting effects. and the light irradiation intensity of the known LED lamps is inversely proportional to the projection distance. Even if the angle of the LED is adjusted, the illuminance on the surface of the illuminated object still cannot achieve the effect of uniform distribution, and there is a problem of decreasing luminosity in the surrounding area.

Utility model content

The technical problem to be solved by the utility model is to provide an LED base plate structure, which has the characteristics of simple and quick manufacture, high efficiency and good industrial economic benefits.
